Manila Water is assuring customers in its East Zone concession area of uninterrupted 24-hour water supply as El Niño conditions and reduced allocations from Angat Dam raise supply concerns, supported by key investments in alternative water sources including the now-operational East Bay Phase 1 Water Treatment Plant. Completed in 2024 and commissioned the following year, the P2.7 billion facility draws water from the eastern side of Laguna Lake to deliver up to 50 million liters of treated water daily, serving as a vital new strategic reserve separate from Angat Dam. Equipped with an 8-million-liter reservoir, pumping systems, and advanced treatment processes including dissolved air flotation, activated carbon filtration and reverse osmosis, the plant ensures safe quality while strengthening overall supply reliability during dry spells and climate challenges.
The facility was built to meet rising demand in Rizal province and add extra capacity to the wider distribution network, giving the company more flexibility to manage resources across its service area. According to Manila Water corporate communications group head Dittie Galang, the project reflects long-term planning to diversify water sources and shield customers from supply uncertainties as climate impacts grow more severe.
To further reinforce water security, Manila Water is developing additional projects including the 200-million-liter East Bay Phase 2 plant and the 220-million-liter Kaysakat facility, both nearing completion. It has also expanded its reserves through other sources such as the 100-million-liter Cardona plant, 80-million-liter Calawis plant, and the recently acquired Upper Wawa Dam which can provide up to 710 million liters of raw water daily. These combined efforts form part of ongoing work to build greater resilience against changing weather patterns and ensure stable supply for all customers.
